How to configure anti-DDoS attack proxies? 3 core strategies and real-world cases

Underlying logic of anti-DDoS attack proxy configuration

The old iron who has engaged in website operation and maintenance all know that DDoS attacks are like the mudslide in the network world - instantly can wash down the server. At this time the proxy IP becomes a lifesaver, but many people configure the wrong way. Remember the core principles:Divert attack traffic with dynamic IP clusters and rely on intelligent routing to direct malicious requests to black holesThe

ipipgo's Dynamic Residential Agent has a trick up its sleeve:90 million + IP poolsIt's like a mobile moat. The attacker has just locked an IP, our rotation mechanism has already switched a dozen addresses. Here's how to do it: set the IP's time-to-live to3-5 minutes, more aggressive than the regular setup, so that the attacker can never catch up with you.

proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://ipipgo_rotating_pool;
proxy_next_upstream error timeout invalid_header;

Three Practical Strategies Explained

Strategy 1: Cellular Defense Network
Don't put your eggs in one basket! Decentralize business traffic to proxy nodes in different geographic regions. For example, an e-commerce site could play like this: US users go to the Chicago node, European users go to the Frankfurt node, and Asian users go to the Tokyo node. ipipgo'sCity-level positioningThe function is so good that you can just check the target city in the console.

Strategy 2: Traffic Fingerprinting
Add a behavioral analysis module to the proxy layer. When an IP is in the50+ requests launched in 10 seconds, which automatically triggers the validation mechanism. Here's a pitfall to watch out for: don't use traditional CAPTCHA, instead use theJS challenge + TCP protocol obfuscationipipgo's Enterprise package comes with this feature, so remember to turn it on when you configure it!Intelligent Behavioral AnalysisSwitches.

Strategy 3: Dynamic Black Hole Routing
This is our one-of-a-kind secret. When abnormal traffic is detected, automatically createFalse response nodeThe attack traffic is directed to these "honeypots" and real users go through clean channels. Attack traffic is directed to these "honeypots" and real users take the clean channel.

Real Customer Case Review

Last year, a cross-border e-commerce company was hit with a hybrid attack of 800Gbps on Double Eleven. We did three things with ipipgo Enterprise Edition dynamic proxy:
1. InitiationEmergency IP pool expansionThe new IP address is 3 million temporary IP addresses in 15 minutes.
2. Openingprotocol obfuscation mode, masquerading HTTP requests as video streams
3. Enablinggeofence, directing anomalous traffic to the Antarctica node
As a result, the cost of the attack dropped from $500/hour to $50/hour, and the site didn't drop throughout.

Frequently Asked Questions

Q: Which package should I choose for a small or medium-sized website?
A: Daily traffic <50GB selectionsDynamic residential (standard)If you have sudden traffic demand, you can purchase a flexible IP package.

Q: What should I do if my website slows down after configuring the proxy?
A: Check three points: ① whether the protocol is selected SOCKS5 ② DNS resolution whether to go EDNS ③ open ipipgoIntelligent Route Optimization

Q: How to respond to a 0day attack?
A: Immediately perform three steps on the console:
1. ClickEmergency protection mode
2. OpeningStrict protocol-wide calibration
3. EnablingSecondary IP Pool

A final word of advice: don't wait until you're hit to remember to buy an agent, do it on a daily basis!IP Pool Warm-upipipgo's static residential proxies are especially suitable for long-term protection, and 500,000+ fixed IPs are like putting bulletproof vests on servers.
